What was reaction when mason wanted to leave in the book Jane Eyre?

It's important to note that Mason, Mr. Rochester's ward, does not express a desire to leave Thornfield in the book "Jane Eyre". It is Jane who desires to leave, not Mason.

When Jane discovers the truth about Mr. Rochester's marriage to Bertha, she is horrified and feels deeply betrayed. She feels she can no longer stay at Thornfield and be complicit in the deception. This is why she leaves, not because of any desire on Mason's part.
